This invention relates primarily to a window screen embodying ventilator features for obstructing vision therethrough.

Extensible screens have been devised; for insertion in the Window frame for obtaining a proper amount of ventilation in the room, and in order to provide a blind or shutter functioning of the screen it has also been proposed to incorporate or embody in the screen make-up a series of overlapping slats or louvers which are also extensible in their nature, :whereby vision-obstruction is ob-v tained without materially affecting the'desiredventilation. Usually these extensible screens or ventilators have been removably inserted in the sash guideways in the window frame and are readily removable from the exterior as well as the interior thereby providing an; easy means of anyone gaining unauthorized entrance into the room. Furthermore,;by reason of the nature of the device, the extensible screen is of a light construction and soon breaks down or becomes distorted after short usage.

The present invention hasfor its objects to provide an improved structure of a stronger and more durable construction; to provide a construction of this character in which the foraminous screen or filler is readily removable as a unit for purposes of repair; and to provide improved means for securing the screen against unauthorized displacement and the window against further openin from the outside.

The invention further resides in. the arrangements and combinations of parts hereina ter more fully described, and the salient features of construction, reference being had to the accompanying drawings wherein:

In proceedin in accordance with the present invention t e combined screen and ventilator comprises sections A and B telesco ically related and each section havin at Its outer end'an upright frame member 1 aving vin its inner face a se'ries of inclined. seats into which are secured the outer ends of the slats 2 and 3. These's lats may be secured g in their seats in any convenient mannersuch as by fasteninv devices 4,",andthe lower slats 2' and 3 combined to form a tubular lower frame member of the screen,"the same having their lower edges extended to form base portions 5, giving depth to the screen frame, and turned upwardly alon their free or inner edges. to provide marginal flanges 6.

The up er or top frame member of the screen bo yis also hollow, having depending slat-forming flanges 2" and 3" with top portions 7 terminating along their free or inner edges in flanges 8 in 0 position to the flanges 6. The slats are te escopically related to each other with the male or hollow slat parts 3, 3 and 3 being received by the female slat parts 2, 2' and 2", the alternate slat parts carried by each upright being of a different type than. the intermediate slat parts. In a other words, the adjacent slait parts 2 on each upright 1 are interposed by a slat part 3, and vice versa. This provides a construction in which the adjacent composite slats overlap in opposite directions so that the breaks in the I adjacent slats will occur in offset or staggered relation and thereby provide for a greater rigidity at the central portion of the screen body; Further, the male slats are preferably shorter than the female slats to avoid binding of the former in the latter at their attached ends, when the screen is fully contracted. The slat parts 2 may be referred bent backwardly upon themselves. Complete separation or withdrawal of one screen section from its companion section is avoided as by turning down a stop lug 26 on one of the slats to engage a stop shoulder 3a on its companion slat. The sto lug 2b is inclined outwardly to facilitate e insertion of the slat 3 beneath the same. An intermediate upright 9 the an The numerals 10 denote foraminous frames .or fillers consisting of a wire mesh fabric bordered by channeled strips 11. The fillers are slidably received through the open inner ends of the screen sections and are secured in rabbetted seats 1 against dis lacement by fastening elements 12 piercing eborder 11 and entering the" adjacent upright 1. The section B is provided with gulding stops 13 to cooperate with the inner flanges 6 and 8 in receiving its screen filler 10 of said section while the spaced pairs of inner and outer flanges 6 and 8 define guidewa s for outer screen filler 10 of the section 7 When it becomes necessary to renew. the mesh 10 the fasteners 12 are removed and the screen filler withdrawn through the inner end of the section as indicated at 14 in Fig. 2. After re air the filler is replaced in its section an accured by its fastening elements.

. Means are also-provided for mounting the screen in a window frame against unauthorized displacement and also in a manner to permit the sash being raised or lowered without removing the screen. Preferably such means contemplates the establishment of an interlock between the screen sections and the window frame C so as to prevent unauthorized collapsing of the extensible screen. In the present showin this meansembodies a air of guides or c anneled retaining memrs 15 fixedly secured to the opposite sides of the window frame and having an inturned locking flange 16 slidably received in a ve 17 formed in the outer face. of the a jacent upright 1. This interlock is effected by introducing the upright through the upper end of the retaining c annel 15 with the flange 16 interlocked slidingly with the groove or slot 17. This provides a construction in' which the screen sections are held a inst collapsing movement without first wit drawin in members.

o prevent unauthorized displacement of the screen from its retainin members there is provided a keeper or lociing member 18 which is movable into the path of the screen to obdruct upward movement thereof. In

the present embodiment this keeper member is lvotally mounted, having a pintle 19 journ ed in a bearing member 20, and is arranged for g over the upper end of the adjacent upright 1 The bearing member is provided to connect and brace s 6 and 8 of each screen section, (A and. at its inner end.

20 ma be separate from but is preferably carri and secured to the window frame by the same attachin elements or screws 15' which are employe in mounting the retainin member in place. v

e keeper member 18 has its free end upturned to form a knob 21 by which the lock.

may be readily swun to and from an operative tion. The pintle 19 is held against disp acement from its bearing member 20 b its angularly disposed lower end 22 whic constitutes a limit stop for confining the swinging movement of the keeper 18 within prescribed limits. x

In order to hold the window sash D against being raised unauthorizedly the keeper 18 is extended to overlie the bottom rail of the sash 4 while lowering by an overlying as indicated clearly in Fig. of the sash is prevente keeper plate 23 which is mounted on the sash.

propirwidthmhelatter is inserted downwardough the retainers 15 with the locking ange 16 entering the groove 17. The keepers 18 are now swungto a positionoverlyingthe screen and, if desired, to a position overlying the bottom rail of the sash D and beneath the keeper plates 23, following which the ins 24 are positioned, so, that the screen is t ereby locked in position against unauthorized displacement either upwardly or by telescoping the sections, and the window sash is secured against being raised above the top of the screen or lowered from a set position. The telescopin slat arrangement with the staggered over aps provides an extensible ventilator of the slat type which possessesdurability and rigidness, and the removability of the screen fillers permits the ready repair of the mesh, whereby the entire assembly is capable of being used over a long period of time.

What is claimed is:

1. A window screen comprising a pair of g relatively slidable sections having uprights the screen body upwardly from their retain-J at their remote ends, alternately arranged male and female slats carried by each of the uprights and telescopically related with the female and male slats of the companion upright, said male slat bein shorter than the female slat to avoid bin ing in the latter, and cooperating parts carried by said slats for preventing total displacement of one slat from the companion slat.

2. combination with upright channeled retainlng members secured to the opposite sides of a window frame, of a window screen all upon vertical movement of the screen, a

keeper carried on one of the retaining members, said keeper being pivotally mounted on the retaining member for swinging into engagement with the screen to secure the latter against vertical displacement from the retaining members, the free end of the keeper being extended to engage with a sash in the window frame, and means for connecting the free end of the keeper to the sash to thereby hold the latter against unauthorized movement.

4. In combination with a window frame having a sliding sash, an extensible screen arranged within the frame, a pair of opposed retaining members secured to the opposite sides of the frame adjacent the sash and receiving the screen, means interlocking the screen with said retaining members against collapse, and means carried by the retaining members for locking the screen against displacement therefrom and for holding the sash against movement.

5. In combination with a window frame having a sliding sash, an extensible screen arranged within the frame, a air of opposed retaining members secure to the opposite sides of the frame, means slidably interlocking the screen with said retaining members against collapse and displaceable therefrom upwardly, and a keeper member pivoted on each retaining member for swinging to a position to overlie the screen to prevent unauthorized displacement thereof.

6. A window screen comprising relatively slidable sections, and channeled retaining members attachable to the window frame at opposite sides and each receiving the adjacent sections and having an inturned flange for interlocking therewith to hold the sections against contraction.

7. A window screen comprising a pair of relatively slidable sections aving male and female slats telescopically related, one of the female slats being of channeled formation with one of the flanges of the channel provided with a sto lug, and a. cooperating shoulder carried y the cooperating male slat for coacting with the stop lug to prevent complete separation of the slidable screen sections, said stop lug being yieldable and inclined outwardly toward the open end of said female slat to permit said stop lu riding over said stop shoulder upon assemb ing said screen sections.

8. A window screen comprising a pair of frames, guideways formed on the frames adapted to telescope one with the other, and removable mesh filler frames slidably positioned in the guideways of the first mentioned frames.
